CALENDAR s'rnuc'ruu Filed June 5, 1926 /////%/Z4 za Juvrnl'ar Galen Jildez;

calendar structure of simple, durable and inexpensive construction.

A further ob ect 1s to provide a calendar 5 structure or similar article having dials or the like thereon which have indicating numf v p desirableto condense the dials. of'the'struc here to be exposed'through openings in, the front of the device. p Y v r I Still a further object'is to provide some of the-dials in such a device mounted in front of otherones whereby space is conserved and the device is made as smajl'las is practical considering the kind of indicating characters re f quired on the. dials.

Still a furthe r object is to provide a means whereby the indicating characters on both the top and bottom dials are exposed to view at the front of the device withoutinterferring with each other.

With these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my calendar structure, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated inthe accompanying drawings, in which:

Figure 1 is a front elevation of a calendar embodying my invention. v

Figure 2 is a rear elevation thereof.

Figure 3 is a front elevation of the device with the front cover removed; and

Figure 4 is an elevation similar, to Figure .3. with the front disk removed.

I have illustrated my device in connection with a calendar, the back of which is indicated by the reference numeral 10 and formsv a support for the remaining parts.

Rotatably secured to the back; 10 are disks 11 and 12. For securing thedisks 11 and 12 to the back 10, I employ tubular rivets or the like 13. The dials 11 and 12 are used for the purpose of determining the proper calendars to use for any given month of any given year and are not essentially a. part of this invention.

The indicating characters on them areexposed through slots 14 in the back 10. Overlying the dials 11 and 12 is a larger dial 15 rotatably secured to the back 10 by a tubular rivet 16. The dial 15 when used in connection with a calendar, has a set of calendars 17 on its front side. Each calendar is given a number 18'which indicates which day of the week the month indicated by that calendar begins on. Any one of the calendars 17 may provide a sight openin or Aims,- IOWA.

be exposed to view through the frontf19 of the calendar. vTo accomplish this resultfI 'tially the shape of disk115.

In designing a calendar 'or'the'like, it is time whereby a sinall calendar is the, result.

1 This may be accomplished by arranging cerj tain of the dials to overlie others such the dials 15 overlying the 'dials '11 v and 12. A

(Y 20 which is substan a cadendar printed onthe fourth dial 21 isiprovided and rptgt bl I cured to the back 10 by a tubular rivet: It Wlll be notedthat the dial 15 also overliesthe dial 21 in order to conserve space." By

thus over-lappingthe dials 15 and 21, the

problem of exposingtheindicating'charm ters on the dial 21 through a slot 23 in the front 19 of the calendar is encountered.

It may here be mentioned that the indicating characters on the dial 21 consist of the names of the months and the number of'days thereof as indicated by the reference nu- I meral 24.

In order to render the indicating characters 24 visiblethrough the opening 23, I provide an opening 25 in the disk 15 of substantially the same shape as the opening 23 and whic registers therewith when any calendar 17' is exposed through the opening 20. It will be noted that there is an opening 25 correspond ingto each calendar 17 whereby the disk 15 in any of its proper adjusted positions'will allow a portion of the disk '21 to be exposed throughthe opening 23. In order to allow manipulation of the disksll, 12, "1 5, and 21,- Iprovide cut-away portions 26, 27, and- 28 of the back 10. The front 19 is suitably secured to the backlO by rivets or the like 29v whereby thetubular rivets 13, 16,and 22 are concealed. 1 It will be obvious that this device need not bellimited to one having' rotating disks but'would answer as well in a device having sliding parts with indicating characters thereon in which certain of sa d slid- I ing parts overlie others.

Having thus describedmy 1nvention,itwill be seen that I have provided a means whereby indicating characters on certain'disks or the like will be exposed to view throu h openings in the disk overlying them w en the overlying disk is in any of its predetermined adjusted positions.

Some changes may be made in the details of the construction. and arrangement of the parts of my calendar structure and-it ia my port, a pair of sight openingstherein, a inovable member having sets of characters thereon for being selectively-exposed through one of said'si'ght openings, a sight opening in said meinberffor each set characters, each one heing'positionedrelative to'its corresponding eluded Within their scope.
